The problem states "150 mL -> H I". It appears to ask to convert 150 mL to another unit, which is represented as "H I". However, without further context or information about what "H I" represents, we cannot perform the conversion. Assuming "H I" is just a label and the problem is to express the volume, we can assume that the volume is simply 150 mL.

1. Problem Description

The problem states "150 mL -> H I". It appears to ask to convert 150 mL to another unit, which is represented as "H I". However, without further context or information about what "H I" represents, we cannot perform the conversion. Assuming "H I" is just a label and the problem is to express the volume, we can assume that the volume is simply 150 mL.

2. Solution Steps

Since there is no specific conversion rate provided or a clear understanding of what "H I" signifies, we will assume "H I" represents the given quantity expressed as 150 mL.

Thus, the provided volume stays the same.

3. Final Answer

150 mL
